Solar Supporting Frame Difficult to Pull Out by Shimizu Press

The metalworking firm Shimizu Press in Takasaki city of Gunma prefecture developed a new type of supporting frame for solar panels, which is suitable for soft ground and steep slope.

The new technology makes the tips of pillars spiral-shaped, so that the poles are difficult to be pulled out from the land, even in a windy setting for example.
